arraytools

A variety of helpful methods for working with fixed-size arrays.

Examples

Iterator-like methods over arrays:

```rust use arraytools::ArrayTools;

asserteq!([1, 2, 3].map(|x| x+1), [2, 3, 4]); asserteq!([1, 2].zip(["one", "two"]), [(1, "one"), (2, "two")]); ```

Ways to simplify array creation:

```rust use arraytools::ArrayTools;

let mut state = 1; asserteq!(<[; 4]>::generate(|| { state *= 2; state }), [2, 4, 8, 16]); assert_eq!(<[usize; 4]>::indices(), [0, 1, 2, 3]);

let s = "hello".tostring(); // Something !Copy asserteq!(<[String; 3]>::repeat(s).asrefarray(), ["hello", "hello", "hello"]); ```

Conversion to and from homogeneous tuples:

```rust use arraytools::ArrayTools;

let mut array = [2, 3, 5, 7, 11]; asserteq!(array.intotuple(), (2, 3, 5, 7, 11)); array = ArrayTools::fromtuple((1, 1, 2, 3, 5)); asserteq!(array, [1, 1, 2, 3, 5]); ```

Usage

How to use with cargo:

toml [dependencies] arraytools = "0.1"

How to use in your 2018-edition crate:

rust use arraytools::ArrayTools;

Because this needs non-Copy slice patterns, it needs at least Rust 1.31.0.
